China Breaks through Key Technologies of Ultra-light Aluminum Wheels to World Level

Recently, the reporter learned from the Seminar on "Super Lightweight Aluminum Wheel Technology and China's Automobile Industry Development Strategy" held in Beijing that China has reached a comparatively advantageous level in key technologies for ultra-lightweight aluminum wheels. At present, the lightweighting of automobiles has become an important research topic for the development of the global automotive industry, and the key technology is to reduce the weight of the hub.

The results of inspections of Huatai ultra-light aluminum wheels conducted by China Automobile Association Wheel Center Quality Supervision and Inspection Center and Machinery Industry Wheel Product Quality Supervision and Inspection Center show that the three test results of the ultra-light aluminum wheels produced by Huatai Aluminum Wheels Co., Ltd. are all qualified. , And obtained the "AWGP aluminum hub pressure field technology" and "composite aluminum hub manufacturing process technology," two invention patents, to achieve the ultra-lightweight aluminum wheel technology independent innovation.

The relevant research data shows that if the vehicle's overall vehicle quality is reduced by 10%, the fuel efficiency can be increased by 6%-8%; if the rolling resistance is reduced by 10%, the fuel efficiency can be increased by 3%; according to the European Aluminum Association's data, the weight of the vehicle decreases. 100 kg, can save 0.6 liters of fuel per 100 kilometers.

The experts pointed out that if Huatai's ultra-lightweight aluminum wheel technology can be applied, it will increase the production efficiency of China's aluminum wheel industry by 25%, reduce the production cost by 25%, and increase the sales price by 25%. According to China's current annual production of 80 million aluminum wheels, all using ultra-light aluminum wheel technology, in only one year will be able to save 200,000 tons of aluminum materials, worth 3 billion.
